Which energy source has the largest ecological impact on its surroundings?
Urban areas have a high percentage of impermeable surfaces such as roofs and roads. Which of the following changes would you expect to occur in the water cycle?
Read the information and answer the questions.
A coral reef is made up of organisms called corals. Corals are marine animals whose skeletons form the structure of the reef. The bright colors of coral reefs are caused by algae that live inside the skeletons of the corals and provide the corals with energy.
Coral reefs provide homes for about 25% of all marine species. The Coral Reef Ecosystem diagram shows some of the organisms found in a coral reef ecosystem.
When stressed, corals expel the algae, lose their bright colors, and become white. This is known as a coral bleaching event. If the stress lasts for only a short time, the corals can recover. But if the stress lasts for a long time, the corals can starve.
A student claims that coral reef ecosystems are stable because they can recover after a bleaching event.
Which evidence should be collected to evaluate the student's claim?
An increase in the temperature of seawater is one possible cause of coral bleaching. The Global Coral Bleaching Events graph shows the relationship between the change in seawater temperature and three global coral bleaching events.
The change in seawater temperature is correlated with the amount of carbon dioxide in the atmosphere. The Atmospheric Carbon Dioxide graph shows how the amount of carbon dioxide in he atmosphere has changed since 1960.
Scientists claim that an increase in carbon dioxide in the atmosphere destabilizes coral reef ecosystems. Which evidence from the Global Coral Bleaching Events and Atmospheric Carbon Dioxide graphs supports the claim?
Describe what could happen to a healthy coral reef ecosystem if atmospheric carbon dioxide levels continue to increase.
Be sure to include:
- Describe one way a healthy coral reef ecosystem could change if atmospheric carbon dioxide levels continue to increase.
- Describe how that change to a coral reef ecosystem could affect other organisms in the coral reef ecosystem.
